A nurse is assisting with the care of a newborn and is preparing to administer ibuprofen 10 mg PO. Available is ibuprofen suspension 50mg/25 mL. How many mL should the nurse administer? Round the answer to the nearest hundredth, use a leading zero if it applies. Do not use a trailing zero.

Set up a proportion: You have 50 mg of ibuprofen in 25 mL of suspension. You need to administer 10 mg of ibuprofen. Let 'x' represent the unknown volume in mL. The proportion is: 50 mg / 25 mL = 10 mg / x mL 2. Solve for x: Cross-multiply: 50 x x = 25 x 10 Simplify: 50x = 250 Divide both sides by 50: x = 250 / 50 Calculate: x = 5 mL 3. Round to the nearest hundredth: 5mL
